Title: Semiconductor ic device
Inventor: MIHARA TAKASHI
IPC: H01L21/76
Filed: 1983-11-02
Abstract: PURPOSE:To contrive to improve the operating speed by reduction of the parasitic capacitance between the diffused layer under a wiring and a substrate by a method wherein the diffused layer under the wiring serving as the wiring region is subdivided by means of a U-groove isolating region. CONSTITUTION:The diffused layer at the part serving as the wiring region, i.e., an N<-> epitaxial layer 13 and an N<+> buried layer 12 is finely split by the U- groove isolating region 5 so formed as to reach the semiconductor substrate 11. The parasitic capacitance CTS between the layer 12 and the substrate considerably reduces with the decrease in junction area. This leads to the same condition that the wiring capacitance CSO and the parasitic capacitance CTS are connected in series between the wiring L on the surface of an oxide film 14 and the substrate on which a power source voltage VCC such as 5V is impressed. Since the capacitances CSO and CTS are in the same order, the wiring capacitance is reduced to approx. a half in appearance.

Abstract: PROBLEM TO BE SOLVED: To provide a prehardening steel for metal mold for plastic molding, excellent in hardenability and machinability, by specifying respective contents of C, Si, Mn, S, Cr, Mo, V, and Ni in a steel. SOLUTION: The prehardening steel for metal mold for plastic molding has a composition consisting of, by weight, 0.15-0.20% C, 0.30-0.40% Si, 1.00-1.50% Mn, <=0.05% S, 1.70-2.30% Cr, 0.15-0.40% Mo, <=0.20% V, 0.30-0.50% Ni, and the balance Fe. In this composition, the upper limit of Mn content is limited to 1.50% in order to secure required hardenability and improve machinability. Although Si is important in order to improve machinability and remarkable effect can be produced when Si is added by >=0.30%, its upper limit is set at 0.40% because the addition of excess amounts of Si causes deterioration in toughness. Ni is necessary to prevent the precipitation of ferrite in the quench-and-tempered structure of the material and secure hardness, but, when its amount is too much, the base material is made excessively tough and machinability is deteriorated.
